angular velocity
(physics) the rate of change of the angular position of a rotating body; usually expressed in radians per second or radians per minute
 
heat of solution
the heat evolved or absorbed when one mole of a substance is dissolved in a large volume of a solvent
 
acoustic phenomenon
a physical phenomenon associated with the production or transmission of sound
 
tossup
an unpredictable phenomenon
 
calm air
wind moving at less than 1 knot; 0 on the Beaufort scale
 
thermoelectricity
electricity produced by heat (as in a thermocouple)
